I got this cornsnake in Jan. of 2019 at a reptile show as a tiny hatching for a ridiculous price. So, this coming Jan. he'll be AT LEAST 2 years old. Doesn't he look a bit small? Thing is he does NOT like to eat every week (he usually ate every week at first, then he'd refuse food). He has THE weakest feeding response I've ever seen. He seems to prefer every 2 weeks AND he still prefers pinkys to fuzzies (he'll eat a fuzzy every once in awhile, but I have to offer the smallest one I can find, which makes feeding this guy a little more work). Is this normal for a corn?
